Overview
The Fliwin retro-styled e-bike offers a 1000W-3000W peak motor tier, 20 inch fat tires, and a choice of 15, 20 or 35 Ah battery capacity, all backed by UL 2849 certification on the motor, battery and controller.
Fliwin sells this bike across multiple battery capacities, so the range figure (up to 40 miles in the base 15Ah listing) will vary meaningfully with a larger battery option. The listing also mentions a speed limiter set at 20 MPH for safety that can reportedly be removed by following a video guide, which buyers should know before assuming the full 30 MPH top speed out of the box.
- 1000W-3000W peak motor tier options
- 48V 15/20/35Ah removable battery choices
- 20 x 4.0 inch all-terrain tires
- UL 2849 certified electrical system
Who it's for
Suits buyers who want a retro-styled fat tire e-bike for mixed city and light off-road use, and who value UL certification on the electrical components.
What buyers say
From Amazon customer reviews.
One buyer noted the seller proactively confirmed which battery model theirs used before shipping, and it worked correctly through several full discharge cycles. Another called the bike fast, and a third was simply satisfied with the results.
Strengths and trade-offs
Drawn from this product's published specifications.
- UL 2849/2271/2238 certified motor, battery and controller
- Retro styling with reinforced frame welding
- USB-C port for charging devices while riding
- Seller reportedly confirms correct battery match before shipping
- Ships with a 20 MPH speed limiter active, requiring a manual unlock for full speed
- Multiple battery capacity options can make range claims inconsistent across listings
Performance notes
The motor is rated up to 1000W peak with a stated 30 MPH top speed, but ships with a 20 MPH limiter engaged for safety, meaning the higher speed requires an extra unlock step. The 48V battery, offered in 15, 20 or 35Ah versions, drives the range difference between listings, and the reinforced, thickened frame welding mentioned in the description is aimed at handling the extra weight of a heavier battery pack.
